Since the newer hardware may supports different frame size,
so add support to obtain the capability from the firmware

Don't you have to adjust netdev->max_mtu as well when device specifies
max_pkt_len different than HCLGE_MAC_MAX_FRAME?
netdev->max_mtu should be adjusted as well, will fix it.
thanks.
